IMPROVEMENT IN ROTARY HARROWS.

Specification forming part ot Letters Patent No. 1&9, H17, dated March 3l, 1874; appli( ation liled December 29, 1873.

To all whom it may concern.:

Be it known that we, JAMES W. HANGER and JOSEPH H. RYAN, of Clinton, in the county of Henry and State of Missouri, have invented a new and useful Improvement in Rotary Harrow, of which the following is a specication Figure l is a top view of my improved harrow. Fig. 2 is a rear view of the same, and showing indotted lines the position of the harrow-wheels when adjusted for transportation.

Similar letters of reference indicate corresponding parts.

Our invention relates to means for adjusting the pivoted harrows, so as to cause one side thereof' to work deeper in the ground than the other; also, to a spring -connection between the tongue and axle and a caster-wheel, the same also supporting the drivers seat, whereby the weight of the driver effects little'change in the pressure on the harrows in passing over rough ground, while yet exerting a constant spring-leverage on the tongue; and, lastly, to the means of adjustment for the pivoted axles of the harrows.

A is the rear part of the tongue, to the forward end of which is secured, by a bolt, b1, a plate, B, the sides'of which are bent at right angles to project upward along the sides of the said forward end of the said rear part A of the tongue, and through which projecting sides or flanges the saidbolt b1 passes. Through the upper part of the turned-up sides or dan ges of the plate B passes the bolt b2,by which the rear end of the forward part of the tongue is secured to the rear part. The forward end of the rear part A and the rear end of the forward part of the tongue should overlap each other, and be beveled oi' or inclined upon their adjacent sides. The flanged plate' B b1 b2 thus forms a coupling for the joint of the tongue. The rear partAof the tongue is securelybolted to the cross-bar C and cross-beam D. To the frontand rear sides of each end of the .crossbeam D are bolted two plates, E, said plates having longitudinal slots formed in them to receive the said bolts, so that they may be moved out and in by simply loosening them. F are the frames ofthe harrow-wheels, to which are attached the barrow-teeth G. The ends of the bars ot' the frames F are cut oft' at points equally distant from the central points of said frames, and around them is passed a band or tire, H, thus forming wheels. In the centers of the wheels F G H are secured hubs or bearings I, in which litand revolve the journals of the axles J. Upon the other ends of the axles J are formed tenons,which enter the space between the outer ends of the plates E, where they are secured in place by the bolt el. Several holes are formed in the tenon of the axle J to receive the bolt e1, so that the harrow may be adjusted to work deeper or shallower in the ground, as may be desired. of the tenon ol' the axles J is formed a hole to receive the bolt e2, which passes through a hole in the plates E,near the ends of the crossbeain D, when the axles J are turned up into line with the cross-beannbringing the harrowwheels into a vertical position, so that they may serve as transporting-wheels when passing from place to place, as shown in dotted lines in Fig. 2. K are brace-rods, upon the outer ends of which are formed hooks to hook into the holes in the ends of the tenons ofthe axles J, when turned down to bring the wheels F G H into a horizontal position, so that the teeth G may operate upon the ground, as shown in Figs. l and 2. The inner ends of the hook-braces K are slotted longitudinally to receive the bolts by which they are secured to the cross-beam D, so that the braces K may be readily adjusted to correspond with the adjustment of the slotted plates E. The braces K are designed to hold the axles J in a vertical position. The draft-strain upon the axles J is sustained by the draft-rods `L, the rear ends of which pass through holes in the middle parts of said axles, which holes are made larger than the draft-rods, so as to allow the axles to turn upon their pivoting-bolts without its being necessary to detach the -said draftrods. rlhe forward ends of the draft-rods L are inserted between the projecting rear edges of the plates M, attached to the upper and lower sides of the ends of the cross-bar C, where it is secured in place by a pin, several holes being formed in the said edges to receive the said pins, so that the draft-rods L may be readily adjusted, as required. N is a roller or wide-rimmed wheel, which is pivoted to the In the end part forked lower end of the standard O, the upper end of which is pivoted to the under side of the rear part of the block P. The block P is secured to and supported bythe spring-standard Q, the lower end of which is secured to the rear end of the tongue A, or to the center of the cross-beam D, and the upper end of which is secured to the forward part of the lower side of the block P. R is the drivers seat, which is attached adjustably to the upper side of the block P, so that it may be-nloved to the rearward to throw the drivers weight over the caster-wheel N O, or forward to throw his weight upon the harrow. rEhe draft-strain of the caster-wheel N O is sustained by the rods S, the rear ends of which are secured to the side edges of the seat-block D, and their forward ends are secured to the plates M, as shown in Fig. l.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination of the adjustable brace rods K with the harrows F H and pivoted axles J, having` tenons provided with a series of holes, as shown and described.

2. The combination of the caster -wheel N, forked pivoted standard O, block P, supporting seat R, the draft and brace rods S, spring Q, tongue A, and axle D of the machine, as shown and described.

3. The combination of the plates M, provided with a series of holes in their projecting edges, with the draft-rods L, attached to the pivoted axles J of the barrow-wheels F G H, substantially as herein shown and described.
